IceTop: The surface component of IceCube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

IceTop, the surface component of the IceCube Neutrino Observatory at the South Pole, is an air shower array with an area of 1 km(2). The detector allows a detailed exploration of the mass composition of primary cosmic rays in the energy range from about 10 ...

Global electromagnetic simulations of tokamak scrape-off layer turbulence

Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Annamaria Mosetto

In the tokamak scrape-off layer (SOL), turbulent plasma interacts with the wall, determining the boundary conditions for the core plasma, and largely governing the performance of the entire device. In this region, the amplitude of the turbulent modes is co ...

Global electromagnetic simulations of tokamak scrape-off layer turbulence

Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Annamaria Mosetto

We discuss recent studies addressing the properties of tokamak SOL turbulence using a global, electromagnetic, fluid drift-reduced Braginskii model. Non-linear simulations are carried out using the Global Braginskii Solver (GBS) code [1], which is capable ...

Observation Of Cosmic-Ray Anisotropy With The Icetop Air Shower Array

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We report on the observation of anisotropy in the arrival direction distribution of cosmic rays at PeV energies. The analysis is based on data taken between 2009 and 2012 with the IceTop air shower array at the south pole. IceTop, an integral part of the I ...

Quantum oscillations and optical conductivity in Rashba spin-splitting BiTeI

Helmuth Berger

We report the observation of Shubnikov-de Haas oscillations in single crystals of the Rashba spin-splitting compound BiTeI, from both longitudinal [R-xx(B)] and Hall [R-xy(B)] magnetoresistance. Under magnetic fields up to 65 T, we resolved unambiguously o ...

Measurement of the cosmic ray energy spectrum with IceTop-73

Matthias Wolf, Shirit Cohen, Sofia Vallecorsa, Mathieu Ribordy, Xiaoxia Bai

We report on the measurement of the all-particle cosmic ray energy spectrum with the IceTop air shower array in the energy range from 1.58 PeV to 1.26 EeV. The IceTop air shower array is the surface component of the IceCube Neutrino Observatory at the geog ...

Cosmic ray composition and energy spectrum from 1-30 PeV using the 40-string configuration of IceTop and IceCube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

The mass composition of high energy cosmic rays depends on their production, acceleration, and propagation. The study of cosmic ray composition can therefore reveal hints of the origin of these particles. At the South Pole, the IceCube Neutrino Observatory ...

Research and calibration of acoustic sensors in ice within the SPATS (South Pole Acoustic Test Setup) project

Mathieu Ribordy

We present development work aiming towards a large scale ice-based hybrid detector including acoustic sensors for the detection of neutrinos in the GZK range. A facility for characterization and calibration of acoustic sensors in clear (bubble-free) ice ha ...

Background studies for acoustic neutrino detection at the South Pole

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

The detection of acoustic signals from ultra-high energy neutrino interactions is a promising method to measure the flux of cosmogenic neutrinos expected on Earth. The energy threshold for this process depends strongly on the absolute noise level in the ta ...

Design and performance of the South Pole Acoustic Test Setup

Mathieu Ribordy

The South Pole Acoustic Test Setup (SPATS) was built to evaluate the acoustic characteristics of the South Pole ice in the 10-100 kHz frequency range, for the purpose of assessing the feasibility of an acoustic neutrino detection array at the South Pole. T ...
